2017-04-04Error: Added PandocOptionError.John MacFarlane1-0/+2
2017-04-02Text.Pandoc.App: Throw errors rather than exiting.John MacFarlane1-1/+10
These are caught (and lead to exit) in pandoc.hs, but other uses of Text.Pandoc.App may want to recover in another way. Added PandocAppError to PandocError (API change). This is a stopgap: later we should have a separate constructor for each type of error. Also fixed uses of 'exit' in Shared.readDataFile, and removed 'err' from Shared (API change). Finally, removed the dependency on extensible-exceptions. See #3548.

2017-02-19Error: added PandocMakePDFErrorJohn MacFarlane1-0/+2
2017-02-10Added Text.Pandoc.Logging (exported module).John MacFarlane1-8/+3
This now contains the Verbosity definition previously in Options, as well as a new LogMessage datatype that will eventually be used instead of raw strings for warnings. This will enable us, among other things, to provide machine-readable warnings if desired. See #3392.
2017-01-25Generic instance for PandocError.John MacFarlane1-1/+2
2017-01-25Error: change type of handleError.John MacFarlane1-11/+11
It now lives in IO and gives a proper message + exit instead of calling 'error'. We shouldn't be making it easier for people to raise error on pure code. And this is better for the main application in IO.

2016-08-06Fix out of index error in handleErrorMatthew Pickering1-4/+8
In the latex parser when includes are processed, the text of the included file is directly included into the parse stream. This caused problems when there was an error in the included file (and the included file was longer than the original file) as the error would be reported at this position. The error handling tries to display the line and position where the error occured. It works by including a copy of the input and finding the place in the input when given the position of the error. In the previously described scenario, the input file would be the original source file but the error position would be the position of the error in the included file. The fix is to not try to show the exact line when it would cause an out-of-bounds error.

2015-11-09Revert "Use -XNoImplicitPrelude and 'import Prelude' explicitly."John MacFarlane1-1/+0
This reverts commit c423dbb5a34c2d1195020e0f0ca3aae883d0749b.
2015-11-08Use -XNoImplicitPrelude and 'import Prelude' explicitly.John MacFarlane1-0/+1
This is needed for ghci to work with pandoc, given that we now use a custom prelude. Closes #2503.
